The Raw Materials Genetic Type Effect on the Water-Reducing Additives Effectiveness

Abstract

Due to the variety of the tasks solved by modern construction, the properties of Portland cement are far from optimal in all cases. One of the ways of deep modification is to obtain the composite binders on its basis, the properties of which largely depend on the mineral additive. The right choice is a kind of art, it is based on transdisciplinary principles. Another modern trend of concrete technology is the use of water-reducing additives. In this regard, the article considers the influence of the genetic type of the mineral additive in the composition of the composite binder, on the features of its interaction with a number of common superplasticizers. Criteria for the selection of rational combinations, taking into account the characteristics of the use of composite binders, are proposed.
